Part of the Paraje Natural Marismas del Odiel, the Lagunas de Palos y las Madres covers 693 hectares and consists of four lagoons: La Jara, Las Madres, La Mujer and Palos. They are the remains of what once was a nearly continuous line of coastal lagoons linking the marismas at the Odiel-Tinto confluence and those at the Guadalquivir estuary.

The beaches on the coast in the municipality of the inland town of Moguer are actually closer to Mazagon and the famous Doñana Natural Park. This 100-metre wide beach gets its name from the Parador Hotel located here. Playa del Parador is located just a few kilometers from Mazagón along the A494 road but feels like a different world.

Moguer is situated north of Palos de la Frontera and is still very much one of the three significant places in the history of Christopher Columbus and the discovery of America. It has about 21,300 inhabitants.
